文摘
Electron tomography and high-resolution transmission electron microscopy were used to characterize the unique three-dimensional structuresof helical or zigzagged GaN, ZnGa2O4, and Zn2SnO4 nanowires. The GaN nanowires adopt a helical structure that consists of six equivalent<0
11> growth directions with the axial [0001] direction. We also confirmed that the ZnGa2O4 nanosprings have four equivalent <011> growthdirections with the [001] axial direction. The zigzagged Zn2SnO4 nanowires consisted of linked rhombohedrons having the side edges matchedto the <110> direction and the [111] axial direction
